No existe el fichero a cargar - readline (Error de carga)

Question

Cuando quiero para ejecutar Rails 3 de la consola, que arroja el siguiente:

$ script/rails c 
/usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (Load Error) 

He intentado instalar libreadline-dev:

$ sudo wajig install libreadline-dev

Pero cuando lo intenté de nuevo, se lanza tha mismo otra vez:

$ script/rails c 
/usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError) 
    from /usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `require' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `<top (required)>' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `require'

    from script/rails:6:in `require' 
    from script/rails:6:in `<main>' 

Entonces, trato de instalar readline usando rvm:

# rvm pkg install readline 
Fetching readline-5.2.tar.gz to /usr/local/rvm/archives 
Extracting readline-5.2.tar.gz to /usr/local/rvm/src 
Applying patch '/usr/local/rvm/patches/readline-5.2/shobj-conf.patch'...

Configuring readline in /usr/local/rvm/src/readline-6.2. 
Compiling readline in /usr/local/rvm/src/readline-6.2. 
Installing readline to /usr/local/rvm/usr 

Pero de nuevo el mismo:

$ script/rails c 
/usr/local/rvm/rubies/ruby-1.9.2-p318/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError)

    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `require' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands/console.rb:3:in `<top (required)>' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `require' 
    from /usr/local/rvm/gems/ruby-1.9.2-p318/gems/railties-3.0.4/lib/rails/commands.rb:20:in `<top (required)>' 
    from script/rails:6:in `require' 
    from script/rails:6:in `<main>' 

¿Qué más debo probar?

Answer 1

Debo verificar rvm requirements y asegurar que todos los paquetes fueron instalados. Entonces reintall rubí:

rvm reinstall 1.9.2 
Removing /usr/local/rvm/src/ruby-1.9.2-p318... 
Removing /usr/local/rvm/rubies/ruby-1.9.2-p318... 
Removing default ruby interpreter 
Removing ruby-1.9.2-p318 aliases... 
Removing ruby-1.9.2-p318 wrappers... 
Removing ruby-1.9.2-p318 environments... 
Removing ruby-1.9.2-p318 binaries... 
Installing Ruby from source to: /usr/local/rvm/rubies/ruby-1.9.2-p318, this may take a while depending on your cpu(s)... 
ruby-1.9.2-p318 - #fetching 
ruby-1.9.2-p318 - #extracting ruby-1.9.2-p318 to /usr/local/rvm/src/ruby-1.9.2-p318 
ruby-1.9.2-p318 - #extracted to /usr/local/rvm/src/ruby-1.9.2-p318 
ruby-1.9.2-p318 - #configuring 
ruby-1.9.2-p318 - #compiling 
ruby-1.9.2-p318 - #installing 
Removing old Rubygems files... 
Installing rubygems-1.8.18 for ruby-1.9.2-p318 ... 
Installation of rubygems completed successfully. 
ruby-1.9.2-p318 - adjusting #shebangs for (gem irb erb ri rdoc testrb rake). 
ruby-1.9.2-p318 - #importing default gemsets (/usr/local/rvm/gemsets/) 
Install of ruby-1.9.2-p318 - #complete 

Y finalmente funciona:

$ script/rails c 
DEPRECATION WARNING: railtie_name is deprecated and has no effect. (called from <top (required)> at /home/israel/proyectos/d-Formacion/config/application.rb:7) 
/usr/local/rvm/gems/ruby-1.9.2-p318/gems/actionpack-3.0.4/lib/action_dispatch/http/mime_type.rb:98: warning: already initialized constant PDF 
Loading development environment (Rails 3.0.4) 
1.9.2-p318 :001 > exit 

Answer 2

La solución es la combinación de los dos pasos:

1. Instalar libreadline-dev por ejemplo, en una Ubuntu hacer:

   sudo apt-get install libreadline-dev 
   

2. Reinstalar Rubí

   rvm install 1.9.2 
   

Entonces rubí se compilará usando libreadline.

Answer 3

reinstalar ruby ​​es un poco exagerado, puede seguir las instrucciones en esta publicación de blog.

http://vvv.tobiassjosten.net/ruby-on-rails/fixing-readline-for-the-ruby-on-rails-console

instalan libreadline5 y libncurses5

$ sudo aptitude install libreadline5-dev libncurses5-dev 

luego recompilar y reinstalar la línea roja

cd ~/.rvm/src/ruby-1.9.2-p180/ext/readline 
ruby extconf.rb 
make 
make install
